What gear shift is L?
L stands for Low — the Low gear or Low range setting found on many automatic transmissions. It keeps the engine in a lower gear to maximize torque at low speeds and provide engine braking, typically used on steep hills, when towing, or during long descents.
What L does in practice
The L position restricts upshifting to higher gears, keeping revs higher and delivering more power at low speeds while also enabling engine braking when you let off the accelerator. Not every vehicle uses L identically; some models treat L as first gear, others as a dedicated low-range setting.
Common use cases
The following scenarios describe when drivers typically engage L. They illustrate how this setting changes how the car uses gears compared with standard Drive (D) or intermediate settings like 2 or 1.
- Starting or climbing in steep terrain to maximize torque and prevent lugging.
- Descent control to slow the vehicle with engine braking rather than relying solely on the brakes.
- Towing heavy loads where maintaining a low speed with strong torque is beneficial.
- Low-traction starts in ice or snow on some vehicles, though this varies by model.
- In some hybrids, L enhances regenerative braking; in others, it functions the same as a low gear but with different energy recovery behavior.
Note: Using L in normal highway driving increases engine RPM, reduces fuel economy and may feel loud or revvy. It is not intended for regular cruising.
How to use L safely
To use L effectively, check your vehicle’s manual because implementations vary. Engage L when you need extra torque at low speed or enhanced engine braking, then shift back to D or another appropriate mode when conditions allow. Avoid leaving L on flat highways for long periods unless your vehicle is designed for that use.
Summary
The L gear is the Low setting on many automatic transmissions. It keeps the engine in a lower gear to provide more torque and greater engine braking at low speeds, making it useful for hills, descents, and towing. For everyday driving, use D and reserve L for the specific conditions described above, per your vehicle’s manual.
